Toshniwal sensing devices offers dust density meters [model ddm-2001]. This dust density meters find its application in are online pollution monitoring systems, which continuously detect and indicate the dust density in exhaust gas discharged from industrial chimney or stack. Dust density meters instruments are developed using advanced dust collection technologies that support the solution of suspended particular matter [spm] problems. Dust density meters obeys light scattering method for continuous detection with high sensitivity and without any bothersome adjustments. Remote fibre optic detector and built-in air purging facility ensure long time maintenance-free operation. Salient features include: light scattering method no deviation of light axis built-in air purge high accuracy span and auto-zero adjustment useful data outputs minimal running cost and use in adverse environment. The dust density meters are indispensable systems for factories that have large furnaces/kilns. In case dust density is higher than preset level, they provide an immediate alarm to the operator for corrective action like replacement of filter bag thus preventing major pollution accident. Data can be saved as evidence and later analysed for more efficient preventive measures in the future.
